hey emilyanne,
to me, nectar isn't that brown, it's more of a neutral deeper red. i don't have clinique's black honey so i can't say if it is different

sorry.
on my lips, nectar is very similar to the picture that you linked us to; maybe just a touch deeper.
when I wear tender, my lips just look more shiny; there is no real color change (it's very sheer and the color is very near to my natural lip color). nectar just gives them that extra depth and beautiful "oomph." i think darling and maiden are more pink/peachy than red.
i do have a vox page where i have swatched all the SN lippies that i have on my lips--it's
www.testqueen.vox.com and you can see nectar, tender, and my natural lip color in natural light photos. i am actually trying to update it right now with 3 additional lippies (bloom, fearless, and a limited edition liquid gloss that karen gave out awhile ago called lola).
have you looked at sweetheart too? i remember jen and karen both recommending that one as well.
there are other reddish glosses (rare berry, reddy, hotblooded, jaybird) but i don't think those are quite what you are looking for...
i'm hoping jen or someone else will also chime in with their opinion...

if course, my real opinion is that you should just buy all of them

heh heh.
